The invention relates to a holding device, an assembly having a holding device and a rack server slot of one unit.
Rack server slots are manufactured in predetermined height units so that various rack server slots of one unit or two units, for example, can be offered in a standardized fashion. Thus, a rack server slot of one height unit has to fulfil this standard. However, this results in the construction space inside a rack server slot being strongly limited. This can particularly be seen when mounting various components, the size of which was designed for other computer systems.
The object of the invention is to provide a holding device, an assembly as well as a rack server slot, which allow installation components to be advantageously arranged in a rack server slot.
According to a first aspect of the invention, the object is achieved by a holding device. The holding device serves for securing at least a first expansion card in a rack server slot of one height unit. Incidentally, the holding device comprises a base body and a first holding tab, which is arranged on a first side of the base body and configured to secure a riser card and a module on the holding device. Furthermore, the holding device comprises at least a second holding tab on a second side of the base body opposite the first side, which is configured to secure a first expansion card on the holding device.
The holding device is designed for a rack server system of one height unit, so that the holding device can be mounted in such a rack server system. A module and a riser card can be mounted on the first holding tab. In addition, a first expansion card can be mounted on the second holding tab and thus be accommodated in the rack server system via the holding device. In this way, installation of an additional component in the rack server system is made possible, which would otherwise not fit into the rack server system.
According to an advantageous embodiment, the base body is formed in the shape of a frame. The base body is configured to receive a mounting bracket of a second expansion card. The base body comprises a slot tab and a protrusion. The mounting bracket can be inserted in the slot tab and be placed onto the protrusion. Thus, the second expansion card can be secured to the frame-shaped base body instead of the module.
The holding device, thus, may receive an additional, second expansion card instead of the module. In this way, two expansion cards can be accommodated one above the other in one rack server slot of one (height) unit.
According to another advantageous embodiment, the holding device comprises two second holding tabs each having a fastening device for the first expansion card. The fastening devices are spaced from one another in accordance with a standard of the first expansion card.
The first expansion card is stably secured to the holding device by a second holding tab. Thus, the holding device as a whole, in particular the base body, is additionally stabilized via the rigidity of the first expansion card.
According to another advantageous embodiment, the holding device is formed integrally.
An integral design is advantageous for the mounting process, since working steps can be omitted. The holding device is formed of a metal part such as sheet metal by means of punching or bending, for example. Just as well, the holding device can be manufactured from a plastic material as an injection molded part.
According to another advantageous embodiment, the standard of the first expansion card and/or a standard of the second expansion card is a PCIe standard.
PCIe cards have large dimensions and standardized plugs. These plugs are used for electrically contacting the PCIe cards. In addition, the PCIe cards are fixed to the riser card by the plugs. The PCIe cards can be secured to the holding device via standardized bores.
According to a second aspect of the invention, the object is achieved by an assembly having a holding device according to the first aspect. The assembly further comprises a riser card having a first port or having a first and a second port for expansion cards, which are secured to the first holding tab. Furthermore, the assembly comprises a first expansion card, which is secured to the at least one second holding tab and operatively plugged into the first port of the riser card. In addition, a module is secured to the first holding tab.
Accommodating a single PCIe card in a rack server slot in one height unit is a challenge already. To that end, there are riser cards that put a port for these PCIe components in a horizontal plane so that the large expansion cards can be mounted in the rack server slot horizontally. However, almost the entire height of the rack server slot is used as a result. By arranging the expansion card via the holding device according to the first aspect, a module can additionally be mounted in the rack server slot.
According to an advantageous embodiment, the module comprises an electric energy storage.
In the case of a power failure, e.g. the first expansion card or as well further components can still be supplied with energy by the electric energy storage. In this way, the rack server system can be shut down in a well-controlled manner in order to prevent data loss. The module is a battery, a battery pack or a capacitor, for example.
According to a third aspect of the invention, the object is achieved by an assembly having the holding device according to the first aspect. Incidentally, the assembly comprises a riser card having a first port and a second port for expansion cards, which is secured to the first holding tab. The assembly comprises an electrically insulating film, which is arranged between the first port and the second port. Furthermore, the assembly comprises a first expansion card, which is secured to the at least one second holding tab and operatively plugged into the first port of the riser card. Furthermore, a second expansion card is secured to the holding device via a mounting bracket and operatively plugged into the second port of the riser card.
Securing two expansion cards to one holding device that can be inserted in a rack server system of one (height) unit is enabled by the electrically-insulating film, whereby the distance between the two expansion cards can be minimized. As a result, it is excluded that the first expansion card causes a short-circuit in the second expansion card or vice versa.
According to an advantageous embodiment, the first port and the second port are arranged offset to one another on the riser card.
Incidentally, the two ports on the riser card are arranged in such a way that the distance between the base body of the holding device and the two ports is of a different size. Now, if expansion cards of the same standard, e.g. the PCIe standard, are plugged in the ports, the components are offset on the PCIe card and additional space is obtained, which can be used for construction heights of the PCIe cards. In particular, a port contact bar of the second expansion card is not bent or displaced by components of the first expansion card of the circuit board of the first expansion card, so that the port contact bar of the second expansion card rests on a certain position on the base body. In this case, no port contact bar is provided on the first expansion card.
According to an advantageous embodiment, the electrically insulating film has an angular U-shaped region. A first surface for insulating the first expansion card and a second surface protrude from a base surface of the angular U-shaped region. Incidentally, the width of the base surface corresponds to a distance of the first port to the second port of the riser card. The second surface can be latched with a protrusion of one of the two ports of the riser card.
Due to this construction of the insulating film, the insulating film can be plugged onto the riser card and is retained by the two ports. In addition, the insulating card rests against the at least one second holding tab, for example.
According to a fourth aspect of the invention, the object is achieved by a rack server slot of one height unit having an assembly of the above kind.
By the arrangement in the rack server slot, accommodation of multiple components in a kind of sandwich-like structure is realized in a rack server system of merely one (height) unit.
According to an advantageous embodiment, a main board having a plug-in slot for a riser card is arranged in the rack server slot. The main board comprises a recess next to the plug-in slot. Incidentally, the riser card of the assembly is plugged into the plug-in slot, so that the first expansion card is arranged in the region of the recess.
The entire space between a bottom part of the chassis of the rack server slot and a cover part of the rack server slot can be used for the assembly. The construction height of the main board and the fastening process thereof in the chassis is additionally available.
The invention will hereinafter be described in greater detail by means of exemplary embodiments and figures. The figures show in:
A first holding tab 12 is arranged on the base body 11. In this case, the first holding tab 12 is arranged at a first side 13 of the base body 11 and bent away from the rectangular frame of the base body 11 at a right angle. The width of the first holding tab 12 essentially corresponds to the width of the base body 11.
In addition to the first holding tab 12, two second holding tabs 14 are arranged on the base body 11. However, in other configurations, the two holding tabs 14 can be combined in a single holding tab 14. The two holding tabs 14 are arranged at a second side 15 of the base body 11 and are thus located opposite the first side 13 from the recess of the frame-shaped base body 11.
A riser card 18 can be secured to the first holding tab 12 via fastening tabs 26. Furthermore, the first holding tab 12 comprises a fastening device 27. In the exemplary embodiment, the fastening device 27 consists of three holes formed in the first holding tab 12. In the arrangement according to

The insulating film 21 is arranged between the first expansion card 22 and the second expansion card 23, which electrically insulates the first expansion card 22 from the second expansion card 23. The two expansion cards 22, 23 are plugged into the two ports 19, 20 of the riser card 18 and are thus operatively connected with the riser card.
When the assembly is plugged into a plug-in slot 30 with a plug contact of the riser card 18 on the main board 29 in a rack server slot 31, both the first expansion card 22 and the second expansion card 23 can be addressed via this electric connection.
Furthermore, connection contacts (not illustrated) of the port contact bar of the second expansion card 23 can be contacted through the opening of the frame-shaped base body 11.
A module 24 is fixed to the first holding tab 12 instead of the second expansion card 23. In the exemplary embodiment, the module 24 is a battery packet, which serves for protection of certain components of the rack server in case of a power failure. Thus, the battery packet can supply a voltage for the first expansion card 22. The module 24 is latched with the fastening elements 28 and thereby secured to the fastening device 27. To that end, the module comprises elongated holes, which have different radii on opposite ends, so that the mushroom-shaped fastening elements 28 can be plugged in at one side of the holes of the module 24 and the module 24 can be clamped therein by displacing the module 24.
